Application filed. 'A1 sust 9, w19. Serial No. 316,246.

To all whom t muy @ancora citizen of the United States, and rosi'.. at .lltoona`l` Blair county, State ot ljenofylvania, have invented certain new and nsf` ul improvements in Lubricators, ot which the following is a specilication.

The present invention relates to lubricating device, and more particularly to a mechanical lubricator adapted to discharge lubricant against a pressure.

According to the present invention the lubricator includes a collapsible container adapted to hold a liquid lubricant, and means to collapse the cont er to expel. the lubricant. More particularly the container is ot metal and has side wallsadaptcd to permit the container to be collapsed. 'lectures ot' the'invention reside in the for subjecting the outside of the container to a pressure substantially equal to the pressure within the container, thus tending to oppose any distortion of the container; and the provision ot moans whereby the container may be charged with lubricant with out removing the container troni its snpport. Other features consist in thegcneral combination and arrangement ot the parts constituting the device.

The objects and features of novelty of the invention will be apparent from the description taken in connection with the drawings, in which- Figure l is a sectional elevation through a lubricator constructed in accordance with the present invention;

Fig. 2 is a plan view, one halt in section ot the lubricator, the section being taken on the line 2-2 of Fig. l;

Fig. 3 is a sectional elevation taken substantially on the line of Fig. 2;

Fig. l is a view in elevation illustrating the manner oit connecting the lubricator to a pressure pipe into which lubricant is to be discharged, and

Fig. 5 is sectional view similar to F ig. l illustrating a modified form of the invention.

Referring to the drawings which illustrate one embodiment of the invention. the numeral l0 indicates a shell, shown as cylindrical, having one of its ends closed by a head ll, andl its other end closed by a head l2, the head ll being secured to the shell as by means ot studs 13, and the head l2 being 'lastejed to the shell by studs 14. Disposed within the shell lO is a collapsible container l5, preferably ot metal, and adapted to hold a liquid lubricant. ln the forni shown, the sido walls ot the container may be corrugated or ot a shape which may be termed accordion walls, as indicated at 16. lt will be seen that this construction permits the container to be collapsed like the bellows ot' an accordion. @ne end o'lf the container open and provided with a peripheral flange l?. which is clamped between the shell and ll, thus securing the container to thc F or the purpose of iilling the coni. with lubricant, the head ll is pro4 vided with a lling opening 19, normally closed by a plug 19. The lubricant is dis charged through a conduit connected as by means of pipe 21 to the point where it is desired to feed the lubricant.

For the purpose of positively7 collapsing the container, mechanism is disposed at the lower end of the container. As shown a nut 22 is rotatively mounted in bearings at and 24- carriefl by the lower head 12 of the shell and a spider il respectively. A. plate 25 is disposed under the bottom ot' the container, and has a stem 26 threaded through 'the nut lt will he seen when the nut 22 is rotated, the plate 25 will be moved vertically. ln order to prevent rotation oT' the plate 25, it is provided with. a peripheral lug 2T slidable` in a keyway 2S formed. 'in the interior of the shell.

Any suitable mechanism may be provided for rotating the nut 22. As shown a worm wheel 29 is connected with the nut, the nut in tact forming the hub ot said wheel. AY shaiit 30 rotatively carried by the head l2. has a worm 8l in engagement with the worm wheel 29. For the purpose ot turning the shaft 30 in either direction, a hand crank 37. may be provided. In the normal operation of the device however 'tor collapsing the receptacle, a ratchet device is provided. As shown this device is mounted within the housing 32 rotatable on the shaft 30, the housing' carrying a pa-wl 33 adapted to cooperati` with a ratchet wheel 34 secured to the shaft 30. rlhus when the arm 35 secured to the housing 32, is oscillated autoth ereof.

matically or manually, the ratchet wheel and shaft 30 will be Vturned in one direction, thereby gradually collapsing the container. After the container has been collapsed, it may be allowed to expand by turning the hand crank 31 in the direction to lower the follower plate 25.

-When the lubricator is used for the pur- 4 -a conduit 36 to the space within the head between the outside oi? the container and the interior of the shell. Thus the pressure within the pressure pipe will be conducted to the shell 10, so that the outside of the container is subjected to a pressure very nearly the same as the pressure on the interior thereof. In cases where the pipe to which the lubricant is applied is a steam pipe, some ot the steam supplied to the head 12 and on the outside of the container will condense.l and a drain 37 previded to allow this condensate to run out, a valve 38 controlling the same. .lt is obvious that if desired this drain may be opened and closed by means ot the usual thermostat diaphragn, such as used in ste/:un heating apparatus orn railway cars.

In the operation oi? thc lubricator, the plate 25 being at the lower end ot its movement, the container is iilled through the opening 18 and closed by the plug 19. rllhen as the arm 35 is oscillated the follower plate 25 will, be moved upward, collapsii the container and exlielling thelubrica t. it the saine time pressure [luid :iii-om the pressure fluid pipe willfbe conducted to tac outside of the container, thereby colualizing the pressure on the interim' and exerior 12, this space connnunicating with the space ln the modified form of the invention illustrated in F ig. 5 the general arrangement of the parts is similar to the device already described. The means 'tor preventing leakage oi lubricant when the `'.Iliinger is operated, however, coniivirises :i device thereof secured to the shell. ln this orm oi' the invention rotation oit the plungerpassage 20. Illhe flange 1.7 ot the collaps ible device being secured to the shell will prevent an lubricant from passing into the lower head 12. As the plunger advances the collapsible wall 16', which may be de-` scribed as an accordion wall, expands to the' position illustrated in dotted lines near the top of the shell l0. The plunger 25 and the collapsible device are returned to the full line position shown in Fie. 5, in the saine manner that the plunger is returned in the :form of the invention shown in F ig. 1. Any pressure acting on the accordion walls due to forcing out the lubricant from the shell. is' counter-balanced by the lu'id pressure acting on the opposite side ol' the walls and introduced to the head 12 through the pipe 36. ln this manner distortion ot the collapsible device is prevented.
